actually make a streaming connection parser in superagent

override the parser, force it to stream.  passes tests, but
haven't used in production to see if close_wait bug is triggered
tests are passing now...wasn't sending query right

the static_webfiles test was failing on oocss stuff, because I am
pulling that from the root of the server, so it isn't there anyway

the db_path test for highway detectors was failing because I was
using superagent's "send" command, not the "query" command.  fixed,
and it passes

dropped some console.log stuff too, not completely clean yet
